According to @EmberCN, HTX will delist PI (IOU) tokens as the Pi Network mainnet is set to launch on the 20th. PI (IOU) holders on HTX will have their tokens automatically converted to USDT at a final trading price of $61.28 within a week post-delistment. Once the mainnet goes live, HTX plans to relist the mainnet PI coins. This transition marks the completion of the PI (IOU) trading phase on HTX.

According to @justinsuntron, USDD is a decentralized stablecoin, ensuring that no external party has the authority to freeze or rug pull funds. Additionally, the yield from USDD primarily stems from subsidies provided by @trondao, which automatically converts USDT to support returns.
